Only what you choose to send us through the concept inquiry form. That form submits to a private database: your name, email address, optional company and link, the type of concept, your description of what you are building and the support you are looking for, your desired timing, and the date and time you submitted.
We also record a one-way hashed value derived from your network address, plus your browser's user-agent string, purely to limit automated abuse. We do not store your raw IP address, and the hash cannot be used to contact or identify you.
Browsing the rest of the site collects nothing. There is no account system, no login, and no user area on this website.
